Abstract (en)

Each of i, k, l, m and t is an integer not less than 2. A parallel signal of a k bit width is converted such that every m bits of width is made a byte, which is then coded by a plurality i of encoders (11) into a t byte error correcting code in which a byte length is of m bits and a code length is of l bytes. The coded parallel signal is interleaved and is distributed into a plurality l of transmitters (21) by an interleaver (4). Each of the transmitters (21) converts the parallel signal of an mi bit width into a serial signal and transmits the converted signal. Each of the receivers (22) converts the received serial signal into a parallel signal of an mi bit width and outputs the signal thus converted. The signals outputted from a plurality i of receivers (22) are deinterleaved by a deinterleaver (5) and the deinterleaved signals are inputted to a plurality i of decoders (18). The decoders (18) carry out correction of a t byte error in which one byte is of m bits, and integrates the signals outputted therefrom and outputs a parallel signal (2) of a k bit width. By making use of the byte error correcting code, interleaver, and deinterleaver, the parallel data transmission unit enables the correction of a byte error having a byte length longer than that of the code, and also enables the reduction in scale of the encoders and decoders. <IMAGE>
